The side tubes of hurricane lamps are employed for receiving the bearings for the carrying handle and the cranked lever used for lifting the lantern cylinder as well as for supplying air to the upper and lower parts of the lamp.

Hitherto the provision of these bearings, as far as concerns the carrying handle, necessitated additional material and welding, and, as concerns the cranked lever, a diiferent treatment of the tubes belonging to the same lantern since the bearings for the two ends of the lever were differently constructed. In this way the manufacture of the side tubes and therefore of the lamps was made more expensive.

rIhis invention consists in constructing the side tubes of hurricane lamps in such a manner that the provision of the bearings therein causes little additional expense while they are stillarranged in satisfactory manner so that the manufacture of the side tubes and therefore of the lanterns is more economical than hitherto.

This object is obtained according to the invention for the bearings of the carrying handle by the material for the bearing tubes which receive the carrying handle being cut out from the same piece from which the halves of the side tube itself are made so that this is formed in one piece with the section of the side tube. This is possible without increasing the size of the pieces used because the bearing tubes are at the rounded parts of the side tube and these have an enlargement for making the rounded parts which is now utilized for making the ears, while formerly it was wasted.

ri"he ear then has on its outer edge a ridge for reinforcing it like the side tube. 'Ihe hole in the ear for receiving the handle may likewise have a ridge at its edge for further stiiening.

In this 'way the construction of the upper bearings in the side tubes is considerably simplified. In order also that the lower bearing places for the cranked lever may be made more simple than before, the bearing surfaces for receiving the two ends of the lever are so constructed that the slots in the side tubes through which they are placed are centrally symmetrical on both the right and the left hand sides. In this way the separate working of the right hand and left hand side tube which was hitherto necessary is avoided and thereby not only is the manufacture made cheaper but also the keeping of stock is simplified.

A consti-fictional example of the invention is illustrated in the accompanying drawing.

Fig. 1 is a side elevation of a hurricane lamp with side tubes constructed according to the invention,

Fig. 2 is a section in the direction of the line II-II of Fig. l on an enlarged scale which shows in particular the construction of the bearing ears for the carrying handle,

Fig. 3 is a part elevation of the side tube on the right in Fig. 1 seen from the inside which shows the construction of the sheet metal bearing for 5 the cranked lever,

Figs. 4a and 4b are sections on the line IV-IV of Fig. l through the left hand and right hand side tubes respectively.

The hurricane lamp illustrated in Fig. l has substantially the ordinary construction and consequently has on each side the known side tubes Si and S2. At the upper ends of the side tubes are the bearings for the carrying handle B and at the lower ends those for the cranked lever H. 7.5

Each bearing for the carrying handle consists of an ear l which at its centre has a hole 2 for taking the carrying handle. The ears 1 are made in one piece with the side tubes Si and S2 by being cut out from the pattern pieces of the two sections of the side tubes. The outer edge of the ear has a ridge 3, as is shown in Fig. 2, which is formed by rolling the one section of the side tube into the other. The other section of the side tube is folded over the rst one at 4 at the edge of the hole 2, as is also shown in Fig. 2. In this way the two sections of the side tube are securely fastened together so that welding is unnecessary.

At the bearings of the lower ends of the side tubes for the lever H, two sheet metal bearings 5 and 6 are arranged. These are made of the same shape in the parts which pass through the side tubes S1 and S2 so that the slots in the side tubes can also be made similar. Each side tube has a shorter slot 7 on the outer side through which passes a shorter bent over tongue 8 of each sheet metal bearing and a longer slot 9 on the inner side. 'Ihe outer slot 7 lies in Fig. 1 in the left hand side tube at the front and in the right hand side tube in the back, and the inner slot 9 lies at the back in the left hand side tube and at the front in the right hand side tube.

'Ihe two sheet metal bearings 5 and 6, after passing through the side tubes, are bent over at right angles to form tongues 10 and 1l to receive the lever H. The left hand tongue l0 simply has a hole 12 for the end of the lever to pass through, While the right hand tongue, in addition to a hole 13 for the end of the lever, also has the known supporting surface 14 for the end of the handle of the lever. In order that the tongue 11 may be firmly secured to the arm it is extended beyond the part 6 on both sides of this part.

What I claim is:

1. A side tube for hurricane lanterns comprising half tubes, the lengthwise edge of one of the half tubes being beaded around the corresponding lengthwise edge of the other half tube, ears integral With the half tubes, arranged symmetrically opposite each other and provided with a central aperture for receiving a carrying handle, one of the ears having its edge beaded around the corresponding edge of the other ear and around the central aperture, the beaded joint of the ears forming a continuation of the beaded joint of the half tubes.

2. A side tube for hurricane lanterns, comprising half tubes joined lengthwise along their edges, the half tubes provided with slots for a bearing bracket of a lifting lever the slots arranged in each half tube symmetrical to the vertical axis of the lantern and at the same distance from the lower ends of the side tubes, so that the half tubes are interchangeable with each other in pairs.
